Every 250th ICMP echo request

Every 250th ICMP echo request to a VIP on my BIG IP appliance times out. Is this a security feature or why does this happen?

Devcentral is intended for programmatic issues with icontrol, irules, advance scripting etc. I think it's best if you call F5 support to see if you aren't hitting a bug or a configuration issue.
